A near-production prototype of the 2016 Audi A4 (B9) has been caught on camera during final testing rounds on the Nordschleife in Germany.

One of the most popular cars ever among spy photographers, Audi's long-awaited all-new A4 is the star of yet another spy video ahead of an official reveal set for September at the Frankfurt Motor Show. We've talked numerous times about the evolutionary design so there's no point in reiterating the cosmetic tweaks brought by the B9 generation.

While the styling certainly won't be appreciated by everyone, a 100 kg (220 lbs) weight loss will, as switching to the MLB Evo platform will bring this rather significant (estimated) diet. In previous spy shots we noticed it's getting the free-standing display as other recent Audi models while the dashboard will feature those interconnected air vents as seen in the new Audi Q7 (and Volkswagen Passat B8).

A report issued back in February by Spanish media indicated the availability of a wide array of engines, as follows:

  • 1.4 TFSI COD (cylinder on demand) with 125 HP and 6-speed manual gearbox;
  • 1.4 TFSI with 150 HP and 6-speed manual / 9-speed S tronic;
  • 1.4 TFSI COD with 180 HP and 6-speed manual / 9-speed S tronic;
  • 2.0 TFSI with 190 HP and 6-speed manual;
  • 2.0 TFSI quattro with 245 HP and 9-speed S tronic;
  • 2.0 TFSI quattro hybrid with 225 HP + 35 HP (electric) and 9-speed S tronic
  • 3.0 TFSI quattro with 272 HP and 9-speed S tronic;
  • 1.6 TDI with 120 HP and 6-speed manual;
  • 2.0 TDI with 125 HP, 150 HP, 177 HP and 6-speed manual / 9-speed S tronic;
  • 2.0 TDI quattro with 177 HP, 190 HP and 6-speed manual / 9-speed S tronic;
  • 2.0 TDI with 220 HP and 6-speed manual;
  • 3.0 TDI quattro with 218 HP, 260 HP and 9-speed S tronic.
  • 2.0 TDI e-tron with 190 HP + 136 HP (from two electric motors) and 9-speed S tronic

Since a public debut is set for September at IAA 2015, Audi could decide to reveal the new A4 online in August.
